Hard vs soft water explained

Hard water... is water that contains an appreciable quantity of dissolved minerals (like calcium and magnesium).

Soft water... is treated water in which the only ion is sodium.

Hard vs Soft

As rainwater falls, it is naturally soft. However, as water makes its way through the ground and into our waterways, it picks up minerals, like chalk, lime and mostly calcium, and magnesium, and becomes hard water. Since hard water contains essential minerals, it is sometimes the preferred drinking water. Not only because of the health benefits, but also the flavor. On the other hand, soft water tastes salty and is sometimes not suitable for drinking. So why, then, do we soften our water?

The major difference between hard and soft water can best be seen while doing daily housework. Hard water is to blame for dingy looking clothes, dishes with spots and residue, and bathtubs with lots of film and soap scum. Soap is less effective due to its reaction to the magnesium and calcium that lather is not as rich and bubbly. Even hair washed in hard water may feel sticky and look dull. Already relating ourselves with these inconveniences? But we are not finished, hard water can take a toll on household appliances as well as use up more energy. It would also cause serious damage by scale accumulating inside water pipes, water heater, etc. These scale buildup is also known as mineral deposits or scale deposits. When water evaporates by increasing in temperature, the minerals that are suspend in precipitate causing solidified scale.
